During the 19th century, scientists found that when certain parts of the brain of a person were hurt, he would lose the power of doing certain things. And so people thought that each part of the brain does a different job. But modern research has discovered that this is not so, for it is not easy to show exactly what each part of the brain does.
In the past fifty years there has been a great increase in the amount or research done on the brain. Scientists have found out that the way the brain works is not so simple as people in general may think. Chemists tell us that about 100,000 chemical changes take place in the brain every second. Some recent researches also suggest that we can remember everything that happened to us. We may not be able to think of the things we have heard and seen but it is kept there in the store-house of the human mind. Earlier scientists thought that the power of one’s brain got weaker and weaker as one grows older. But it is plenty of exercise, it keeps its power. It is now thought that is not true. As long as the brain is given plenty of exercise, it keeps its power. It has proved that an old person who has always been active in the mind has a quicker mind than a young person who has done physical work without using much of his brain.In the last century, scientists found that a person would lose the power to do certain things _____.

What is the most popular food in western countries? If you are not sure, statistics might give you the answer.
Every year，some 20 million people walk into restaurants and buy 2 billion sandwiches. Americans alone eat more than 1 billion sandwiches annually. If you lined up all the sandwiches Westerners eat in a year, they would go around the world 13 times!
When John Montagu made the very first sandwich in England in 1762, he couldn't have imagined that it would still be very popular almost 250 years later. There is a campaign starting this month in the US to find the healthiest and best tasting sandwich in the country.
Sandwiches are commonly carried to school or work in lunch boxes or brown paper bags to be eaten for lunch. They are also taken on picnics and hiking trips. Their longlasting popularity lies in their convenience and fast preparation time.
You can put everything you want inside a sandwich. They are easy to clean up after, nutritious and come in hundreds of different kinds.
Wellknown American chef Dave Lieberman adds another reason.“I think people like to touch their food, kids especially. It's just a natural instinct. You don't have to use a knife and fork to eat a sandwich，” he said.
Sandwiches can be hot or cold with almost any kind of filling. One of the most popular kinds is the BLT—bacon，lettuce and tomato. Although it is a simple food, it can still be creative. Sandwiches can be served openfaced, with sushi inside or grilled with delicious fillings.The author intends to________.

“The U．S.Food and Drug Administration(FDA)is considering to put stricter limits over tanning salons(晒黑廊)and wants to ban anyone younger than 18 years of age from using a tanning bed，”an advisory panel(专家团)announced last week.
The panel is calling for tighter controls on the industry such as requiring teenagers to get the approval from their parents before using tanning beds or limiting the use of artificial tanning to a certain age.“Given the absence of any demonstrated benefits，I think it is an obligation for us to ban artificial tanning for those under 18，”said panelist Dr.Michael Olding.
Along with a possible ban for teenagers，the panel also recommended that visible warning labels should be placed either on the tanning machines or in the salons in order to caution tanners of the possible dangers.In addition，the committee decided that stricter regulations and classifications were critical to make the machines safer.At this time the machines are categorized as FDA Class 1 devices，the ones that are least likely to cause harm.In case the FDA decided to change their classification from Class 1 to Class 2，as advised by the panel，the FDA could limit the levels of radiation the machines emit.Class 2 devices include Xray machines and powered wheelchairs.
Getting a tan，whether from a tanning bed or the sun，increases the risk of developing skin cancer.Last year，the World Health Organization's International Agency for Research on Cancer (IARC)declared tanning beds as “carcinogenic(致癌的)to humans”．It was discovered that young individuals in their teens and 20s who use tanning beds on a regular basis have a 75 per cent higher risk of suffering from melanoma(黑素瘤)，the deadliest form of skin cancer.According to the American Cancer Society，melanoma accounted for nearly 69,000 cases of skin cancer in 2009 and will account for most (about 8,650)of the 11,590 mortality cases due to skin cancer each year.According to the passage，what measures will U．S.FDA most probably take?
| A．Banning tanning salons. |
| B．Posing heavier tax over tanning salons. |
| C．Having tighter controls over tanning salons. |
| D．Limiting the number of tanning salons in every state. |
Which of the following suggestions for making tanning salons safer is NOT mentioned?

| C．Professional personnel. |
| D．Parental approval for teenagers. |
What does the writer want to express in the last paragraph?
| A．Tanning in one's youth may mean death. |
| B．Tanning in the sun is safer than on the tanning bed. |

The hottest“green”toy in Germany isn't made of organic or recycled materials.This one has a solar panel and only runs if kids remember to insert bright red “energy stones”that power the space station.Germany，a pioneer in many renewable energy initiatives，is also at the forefront of creating environmentfriendly toys aimed at making kids think about where energy comes from and how much of it they can use，raising awareness through play.A number of hightech green toys are on display at this year's Nuremberg toy fair，which runs through Sunday.
Among them，there are hydroelectricpowered(水电动力的)toy cars，and doll houses with wind turbines and rainwater catchers.The bright green “Future Planet”space station features an inner atrium(中庭)with a fan that is powered by a functioning solar cell.Its aim is to get kids to use their imagination about how energy will be created in the future.
Makers and retailers believe such toys will play an increasingly important role in their future—and that of our kids.“Energy is the question of the future and we are definitely thinking about this as we move ahead，”said Judith Schweinitz，a spokeswoman for Playmobil，maker of the solar panelfitted space station.“It is increasingly being brought into our play concept.”Green toys—which range from those made of sustainable materials to ones like the space station that just raise environmental awareness—make up only a sliver of the $ 84 billion international toy market，but their share is growing，studies indicate.Environmental research firm Earthsense，based in Syracuse，New York，predicts that green toys will account for about $ 1 billion，or 5 percent of U．S.toy sales in the next five years.Parents are smart and they want information about what's in the product.That's what's really driving the market.The hottest “green”toy in Germany is ________.

Americans gave nearly $300 billion away last year. Do you know the reason? Beyond the noble goals of helping others, it is that giving will make them happier.
It is a fact that givers are happier people than non-givers. According to the Social Capital Community Benchmark Survey, a survey of 30,000 American households, people who give money to charity are 43% more likely than non-givers to say they are “very happy” about their lives. Similarly, volunteers are 42% more likely to be very happy then non-volunteers.
The happiness difference between givers and non-givers is not due to differences in their personal characteristics, such as income or religion. Imagine two people who are identical in terms of income and faith, as well as age, education, politics, sex, and family circumstances, but one donates money and volunteers, while the other does not. The giver will be, on average, over 40 percentage points more likely to be very happy than the non-givers.
A number of studies have researched exactly why charity leads to happiness. The surprising conclusion is that giving affects our brain chemistry. For example, people who give often report feelings of euphoria, which psychologists have referred to as the “Helper’s High”. They believe that charitable activity produces a very mild version of the sensations people get from drugs like morphine and heroin.
Of course, not only does giving increase our happiness, but also our happiness increases the possibility that we will give. Everyone prefers to give more when they are happy. Researchers have investigated this by conducting experiments in which people are asked about their happiness before and after they participate in a charitable activity, such as volunteering to help children or serving meals to the poor. The result is clear that giving has a strong, positive causal impact on our happiness, so does happiness on givingAccording to Paragraph 2. We can learn that .
| A．only those people who gave money to charity will be happy |
| B．more givers say they feel having happy lives than non-givers |
| C．those who donate money are happier than those who volunteer |
| D．42% of the volunteers say they are as happy as the non-volunteers |

If a person feels happy, he may .
| A．ask for more donations |
